Double Girder Ladle Overhead Crane for Steel Mill

Type YZ/QDY
Capacity 5TONS-320TONS(customized)
Span 5m-60m(customized)
Applications QDY/YZ series casting overhead cranes are one of the main equipment in the steelmaking and continuous casting process. It is mainly used to add molten iron to the converter in the converter feeding span, hoist the molten steel to the refining furnace on the refining span or lift the molten steel to the continuous casting rotary ladle table on the molten steel span.

Product Introduction

QDY/YZ casting cranes are the main equipment in the steel-making industry. They are used in the steel-making workshop to lift parallel steel and hot metal, and work in high-temperature, dusty and harsh environments. The working level of the whole machine is A7, A8. Other places for lifting molten non-metallic materials and lifting hot solid metals can also be used as reference.

Features

  • 1
    The double girder casting bridge crane is generally the main and auxiliary lifting mechanism, the main lifting mechanism lifts the bucket, and the auxiliary lifting mechanism performs auxiliary tasks such as turning the bucket.
  • 2
    According to the different requirements of users, the double girder cast overhead crane has double beam double track type, double beam four track type, four beam four track type and four beam six track type.
  • 3
    Its gantry hook is mainly used for lifting and transporting tundish, hot metal tank and ladle of various steel plants. The beam body is made of high-quality low-carbon alloy steel with high strength and high temperature resistance. The hook body is spliced and riveted by steel plates to have high strength and flexibility. At the same time, the hook body can freely rotate back and forth, making it easy to hook.
  • 4
    In order to expand the scope of use of auxiliary hooks and better serve the steelmaking process, the main and auxiliary hooks are respectively arranged on the main and auxiliary trolleys with independent trolley operation mechanisms, and travel along their respective tracks.
  • 5
    The hoisting mechanism of the ladle crane is two sets of hoisting mechanisms, double drums, and double motors to meet the needs of steel mills for 24-hour uninterrupted production in steel factory.
  • 6
    The radiation temperature of the lifted molten metal to the forging hook and plate hook does not exceed 300℃.
  • 7
    The radiation temperature of the lifted molten metal to the forging hook and plate hook does not exceed 300℃.
  • 8
    The control method is the cabin control, the operator's cab can be fixed or moving.
  • 9
    The casting crane has advanced technology, novel and creative structure, safe and reliable, economical and durable, and simple hazards, suitable for production operations in harsh environments.
  • 10
    The main beam and the end beam are connected by high-strength bolts, and the lubrication system is standard.
  • 11
    The main beam adopts a wide off-track box beam, and the material is 16Mn steel.
  • 12
    The drive shaft of the crane operating mechanism is connected by a cross-shaft universal coupling.
  • 13
    The lifting and travel speeds can be single speed and stepless speed. According to the actual needs of customers, we can provide customized products.
  • 14
    Multiple safety protection measures, such as overload limiter and alarm, weighing and display, PLC control and fault detection, display, recording and printing system, anti-collision device, special industrial air conditioner, etc.
